The reason I looked at this next census was to see if the childrens ages were consistant, which they are I asked one of the moderators which registration district would Kensal Green/ Rise come under, evidently at some time it was part of Chelsea.
As you can see the other children are not given as Kensal Rise on this one.
I found a birth registration of a
Catherine Johnson Dec.q 1878 Chelsea 1a - 291 so trying to see if she would fit in with the other children.
Although
James H ages gives him born in 1878 , I think this is his actual birth reg.......
James Henry Johnson, Dec q. 1879 Kensington 1a - 4 so its quite pheasable for Catherine to be his sister although I cannot be 100% sure.
But I still cant find her in 1881 though
